IMPROVED RAILWAY-SWITCH.

vSpecification forming part of Letters Patent No. 64,833, dated May 21, 1867.

To all whom it may concern:

Be it known that I, JAMEs S. BROTHERS, of Duncannon, of the county of Perry and State of Pennsylvania, have invented a new and useful Improvement in Railway-Switches and I do hereby declare the following to be an exact description thereof, reference being had to the accompanying drawings, and to the .letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construction of the chair and the adjustable frog in combination.

Figure 'l represents a perspective view of the railway and switch. Fig. 2 shows the construction ofthe square forked ends .of the frog, and Fig. 3 is an end view of the chair.

A represents the common cross-ties; B, the ordinary rails C, the main lever that operates the roller D and levers E E, common to switches. G is the frog or pivot rail, operating at its center in the dovetail ofthe chair H, but without a pivot or bolt running through it. The ends of the frog Gr are forked, and

the top prongs J J operate on the tops of'the chairs K K, While the lower prongs LL move in the dovetails M M of the chairs K K. The chairs K are to be made of cast or wrought iron, and with wrought-iron guards N bolted down across them, to assist in keeping the frog-rail G trom-rising, and under which each opposite corner or prong L of the frog is firmly held. The frog G is adjustedlby a notch'or pins in the lever E.

What I claim as my invention, and desire to secure by Letters Patent, isv The construction of vthe chair K with the adjustable frogG, .when arranged, combined, and operated as herein described, and for the purposes set forth.
